I got more time to work on my scooter this afternoon...I 'think' I have TDC lined up to make the adjustment....
My scooter has about 3100mi on it. I understand that Jim at Sunright recommends about .003in for intake (top) adjustment and .005in for bottom (exhaust).
I believe I have TDC lined up correctly, as shown in the video linked below.
As I talk about in the video below (no adjustment done yet) .003in will not even slide in at all. .002 WILL slide in with very slight tension- so it 'seems' as if I have TDC correct, just that I'm sitting at .002 instead of .003.
If I have TDC correct, then I'd like to go ahead and adjust to .003 instead of leaving at .002 since I've gone thru all the work of taking everything off yesterday.
(while everything is off I am going to seal up a leak in the overflow tank, change the fuel filter, and I think maybe run a circuit from the battery to upfront where I can eventually on another day install a cig lighter outlet with cover.)
Can someone please acknowledge this is what I need to do to line up TDC?
Thanks.

Looks right to me if both rockers have movement your good to adjust the key is that there is to tension from the cam shaft on either one. That does look like TDC though

[EDIT: turns out bottom was actually as I said- but top, in fiddling with it, before I loosened the locknut- and in effect gently lifted it up- there was in reality all the way up to .008in. Feeler gauge .008 would slide in, but .009 would not slide in. So, I left exhaust on bottom alone, at .005 in spec. and adjusted intake on top from .008in back to spec. at real close between a .003-.004]
got tied up for a little bit and ate dinner. Bottom clearance (exhaust) is .005in so I won't mess with that one... going to adjust the top intake up from .002 to .003in.

Sounds good button it up and get on the road. Check it all twice first LOL easier said than done first time, anyway. The slow down on the valves has been a couple of the allen head bolts were hard to get to and my tools were juuuust a little long, so had to adlib a bit. I edited this post scootdawg.proboards.com/index.cgi?action=gotopost&board=200cc&thread=56683&post=550202 above...turns out the intake was way out... at.008, so I adjusted it back to .003 or so. Going to work until midnight, probably won't start getting panels back on tonight though... man, sure was alot of stuff had to come off... or I took alot off anyway... |

It does take a long time the first time. Now you know what it takes though and the next one will be quicker. Don't rush take your time and get it right. One of the benefits to doing your own stuff is that you care enough to do it well...
Blessings to you may your scoot run like a gazelle when you're done and may your knuckles remain unbloodied, or at least heal quickly...

Blessings to you may your scoot run like a gazelle when you're done and may your knuckles remain unbloodied, or at least heal quickly... Thank you, scootnwinn, yes, I knew there would be frustrations, but I looked at this from the outset as a learning experience. Taking a p break for a few mins...upper and lower valve covers back on..and the cover where you get a visual on the TDC is on... Fuel filter changed out earlier today for a visufilter inline...but, I'm not satisfied with the snugness of the hoses to the filter using the OEM clamps, which have no adjustment... I think the OD of the new filter (inlet/outlet) is slightly smaller... tomorrow may get new small adjustable hose clamps and consider taking the OEM filter to the autoparts store for something that may sit in the oem bracket for the fuel filter better than this visufilter I got off ebay... as it sits, the new filter is not being held, can't be- by the bracket...and since it requires a considerable amount of panels off to get to it if it goes bad next time... I best make it secure. Thanks for replying in the thread here...scootnwinn... I know I'm rambling sometimes, but if someone comes along in the future and searches on a keyword that ends up being in my threads on all of this...maybe something I said will give them insight as those threads that I have come upon during this job have given me... |

Hopefully you can find something that will work. Perhaps this will show my roots a bit too much but a little tie wire might help you fabricate a bracket. Happy shopping

Happy shopping Yah, i neglected to say in the above post that I meant the inlet and outlet OD...don't want those slipping off... yah, i do have some zipties and maybe if I get the inlet/outlet hose clamped as tight as I want, a couple of zipties or so will do just fine on securing the filter... I did start the scooter up, a couple of times and ran it for a few minutes...revved up a little bit, don't want to be too noisy for the neighbors... Scooter hadn't been run in two days- temp outside is 57... engine HAD to be cool... yet I did not have to crank for a few seconds, have it not light-off and try again... it started up quickly on hitting the starter button.. first time... maybe a sign of things to come... and that I didn't screw anything up with the valve adjustment... Fuel appeared to be flowing through the new filter also. Going to toss tools in a pile, bring them in and see what I might be able to finish up tomorrow and sunday... Sunday night temps are predicted in the 30's for us. |

Just another tip, although it sounds like you have it under control and it would be late for this one, Pull the engine by hand thru two revolutions before ever starting it, when you mess with the valve train. That way if something is binding or if you have a valve too tight, you can feel it binding without the engine bending stuff up. It may sound overly cautious but, this one simple step can save your engine.

+1 on urbanmechanic
When you rotate the crank (in the running direction only) observe when a valve opens fully. The opposite valve should be fully closed. At this point you can also check clearance and free play on the lifter of the closed valve. This method can also be used for setting the valves on a single cylinder engine (hint)!
Ride on friend.

Thanks guys. Yah, I did start it up lastnight (fri) a few times, and it started quicker than previously it had. Since the weather had cooled down a bit a few times... it might take one or two presses of the starter for it to start. It's 'near' instant now...I was away today, so don't have the panels and all the rest in/on yet.. but might start tomorrow-Sunday.

There are two timing marks on this engine and the mark on the cam gear is just one.

Are you up.and working already? If not get your coffee and get to it Worked some on it this afternoon and this evening...started again today to make sure would start and warm up and idle ok... seems to. Slow going some on the putting back together...next time think I will video it for documentation... Kind of hung up on the seat bucket/seat vs the big foot rest that drops down from top and goes all the way around... in taking a breather, I came in and just pulled up the manual and thought... maybe I should have RTFM...however, I still can't quite in the dark with my floodlight and heater, see exactly how the seat bucket/boot and the footrest that goes all the way around... go together...I'm sure it's at this point frustration, coupled with a long day, coupled with limited light coming from the right angle (up above instead of 500 watts sitting right beside the scooter either being blocked by my body or blinding me from the opposite side  Going to have to pack up tonight and get to bed... have a routine doc appt tomorrow at the VA and will need to catch the bus to the train station for all of that... |

It's always harder in the dark. Hope the doctor visit stays routine.

There are two timing marks on this engine and the mark on the cam gear is just one. Alrighty, I had seen that somewhere, but forgotten it, however, I figured since I got the one lined up and had freeplay at both intake and exhaust valves...that I was likely as near as TDC as feasible. Exhaust was right on .005in (spec) and intake turned out to be as high as .008in... so adjusted it down to spec at .003in... Have run the engine a few times and seems to start up somewhat better than it had the past few weeks with the cooler weather...of the several times I started it the past couple days- most times it started within 1 second... Once it did take a second push on the starter button. |

Now back together and up and running. I just added JATO rockets to my Aeolus 300!
Ok, not really, but when you combine the new plug at DR8EIX at .030 (stock one was .026 way below what the new one is at .030) and boom, that was a night and day difference in itself.
Better than new from plug alone...
Then, checked intake and exhaust valve gaps per the Jim @ sunright recommendation here in the forum (.003 intake, .005 exhaust). Found the exhaust at spec @ .005in , and the intake way out at .008 . I adjusted the intake to .003 or a really tight .004 , it took a few tries... and finally got it all back together tonight...BOOM
It felt like turbo with the new plug, then when I got the valves adjusted in spec, it was like turbo on turbo, then you add in the cold night air tonight.
Also starts now most times on first push of button in first second...

Awesome now ride it daily so it doesn't get jealous of your cage and things will stay good. We might have to do a Texas/New Mexico meet at the border kind of ride someday...

I don't know yet if it's going to be in the next year or two, but a move to ABQ is in the cards...I was caretaker for my mother and father here in DFW . My mom passed away in 2009 here at home, my dad passed away on April 1st suddenly. ABQ was the last place I was stationed in the Air Force until I got out after 20 in 07. My son and some family live in ABQ... nothing tying me down now but $. |
